Abstract: Herein disclosed is a voltage isolation circuit coupled to power supplies. The voltage isolation circuit comprises a series switch group controlled by a first control signal, a parallel switch group controlled by a second control signal, and a first high impedance element. The series switch group comprises a transistor arranged in a first current loop and having two channels connected to one of the power supplies respectively. The first high impedance element, coupled to the transistor in parallel, has a measurement terminal and two ends, connected to one of the power supplies respectively. When the series switch group is conducted, the power supplies are coupled in series in the first current loop. When the parallel switch group is conducted, the power supplies are coupled in parallel in a second current loop. Impedance values measured from the measurement terminal to each end of the first high impedance element are identical.
